ln the invention of a paper tube rolling machine herewith specified and claimed, it is preferred that numeral 1 designate a main base portion of the machine which may be made of any suitable material, such as cast iron, and adapted to have mounted therein a main driving shaft 2 and having keyed thereto a driving pulley 3, which maybe operatively connected with any proper source of power, the drivim-i` shaft 2 being rotatably supported in part by the base portion 1, and bearing members 4, 5, and 6, which may be firmly attached to some suitable foundation. rllhe driving power is transmitted through the pulley 3 and the main driving shaft 2. which has mounted on the inner end thereof a pinion member 7 enclosed by a housing 8, preferably integrally formed from the base portion 1 of the machine and having a cap portion 9 removably attached. T he rotation of the pinion 7 functions to transmit power to a. gear member 10, securely fastened to a shaft 11, which is preferably located above the main driving shaft 2 and held in rotative position by means of the upper sections 12, Y

13 and 14 of the supporting bearings for the main driving shaft 2. Crank member 15 is adapted to be securely keyed or'otherwise to the shaft 11, and pivotally atached to the free end of the crank 15 is a sliding block member 16, which is adapted to cooperate with a slotted cam member 17 having a circular curved portion 18 and a groove or slotted section 19, one end of the cam 17 being pivotally mounted upon the base portion 1, as at 17', the upper end of the cam 17 being adapted to swing in cooperation with a cross head member 20, which functions to slide in a cylindrical cross head guide 21 supported by suitable bearing members 22 and 23 extending from the main body portion or base 1 of the machine. The free or swinging end of the cam 17 is preferably provided with a saddle fork construction 24 as clearly disclosed in the drawings, which functions to engage in slidable position therein suitable roller elements 25 and 26, which may be made of bronze, and are adapted to slip over pins 27 and 2S located in the crosshead 2G'and securely held in position by means of plates 29 and 30, which may be screwed or otherwise in the ends of the pins.

Suitably mounted in the base portion 1 of the machine is a revolving` spindle shaft 31. which is adapted to pass through cross head 2O within the cross head guide 21. rlhe outer end of the revolving spindle shaft 31 may be mounted in a bearing extension 32 and eX- tend a suitable distance there-beyond in order to accommodate a hardened collar portion 33, which is adapted to cooperate with a spring plunger element 34 held in position by means of a bracket 32 suitably fastened to the bearing extension 32; the spring plunger element 34, when pressed against the collar 33,`tends to hold the spindle or revolving shaft in a steady position. Within the cross head guide 21 and at the forward end ofthe revolving spindle shaft 31 are adapted to be located collar portions 36 and 37 which will'A function to revolve with the rotating shaft 31. ln this construction, the cross head 2O not only acts as a bearing for the rotating shaft 31, but also as a means for reciprocating the motion of the shaft. The forward end of the revolving spindle shaft 31 is adapted to b e provided with a tapered recess (se-e Figure 32) 38, into which is adapted to be mounted the inner endof a tubular spindle 39 and held'firmly in position therein by means "i The winding spindle 39 functions in a reciprocatingfmotion within the cross head guide 21 and extends through a nose member 43 mounted in the guide head portion 44, which, together with guide head portion 45, is fastened to the cylinder cross head guide 21 by some suitable means, such as machine screws 46. The spindle shaft 31 is supported therey fore by the guide head portion 44.

` The action by which the revolving spindleV or shaft 31 is made to rotate is preferably as"- follows:

The driving power is primarily transmitted from the driving shaft 2 through a gear 47 mounted thereon, which is adapted to cooperate with a gear 48 mounted upon a shaft 49, which is suitably supported at its ends by bearing members 50 and 51. A beveled pinion 52 is adapted to be securely fastened to the gear 48, the two members 48 and 52 are adapted to revolve freely upon the'Vr shaft 49, which is held stationary in its bearings 50 and 51. The gearing pinion 52 functions to impart rotation to a cooperating beveled gear 53, which is keyed to a shaft 54 rotating in bearings 55 and 56.

On the end of the shaft 56 is adapted to be keyed a mutilated toothed beveled gear y57' to which is fastened a plate 58. The beveled gear 57 engages with a pinion 59, to which is also attached a plate 60, the beveled gear 59 and plate 60 being mounted upon a shaft 61. Thev plates 5S-and60 are formed in such a manner as to remain in contact during a partial rotation of the beveled mutilated gear and automatically releasing themselves when the mutilated face of gear 57 has passed and the teeth come in contact with the cooperating gear 59.y thereby providing an intermitteilt motion to this particular point. The

teeth in mutilated gear 57, coming in Contact with gear 59, will 'function to rotate the shaft 61 at an increased rate of speed owing to the fact that the beveled gear 59 is of a smaller diameter than. vthe mutilated gear 57. The

beveled shaft 61 Vis supported by suitable bearing members 62 and 63.

A beveled pinion 64 is fixed at the endrof shaft 6l and adapted to transmit power to a cooperating gear member 65, which, in turn, is securely keyed or fixed to the lower end of a vertical shaft 66, at the upper end of which is fixed the beveled gear67 adapted to mesh in operative relationship with a cooperating pinion 68, keyed to a shaft member 69, which is supported in suitable bearing elements 70, 71, and 72. The shaft 69 is adapted to extend a distance beyond the supporting element 72 in order to receive in fixed or keyed relationship thereon a silent chain sprocket wheel 73, which is brought into operative relationship by means of a chain or other suitable driving element 741- with another sprocket wheel 75 mounted upon a shaft member 7 6 properly supported by bearings 77 78, and 79 preferably extending in bracket form from the main base portion 1 of the machine. At a suitable position along the shaft 76 is mounted in keyed relationship thereto a gear 80 adapted to mesh with a driving cooperating gear member 81, which is securely fastened. and mounted by means of a sliding key 82 to the revolving spindle shaft 31, thereby providing a means for revolving the winding spindle 39 and its supporting shaft l31. After the spindle shaft 31 has been moved forward to the desired position, the gear teeth in the mutilated gear 57 function to come in operative contact with the gear 59, thereby `providing rotary motion to the shaft 61,

pinion 6l, gear vertical shaft 66, beveled gear and pinions 67 and 68, shaft 69, sprocket wheel 73.r chain 74, sprocket 75, shaft 76, gear 80 to the gear 81, which is keyed to the revolving` spindle shaft 31. The .revolving motion of the spindle and shaft will continue during a single revolution of the gear pinion 59. the diameter of which is carefully determined from the time it takes for the block 16 to travel through the slot 18 in the cam 17. During the backward and forward movement of the winding spindle 39 and its supporting shaft 31. the rotation thereof is stopped by means of the mutilated gear 57 slipping out of mesh with the driving pinion 59. The plates 58 and 60 function to hold the secondary drive, consisting of the beveled gear 59 in stationary position, so that, at the proper time, the mutilated gear 57 will come into positive relationship with the driving gear 59. The plates 58 and 60 are carefully designed and formed in order to cooperate in maintaining the mutilated gear 57 and the Y gear 59 in positive operative relationship with each other. Thes rin@ lunfrer member 3e is adapted to press against the hardened lcollar elements 33, thereby functioning to 15 through the sliding block16 functions t0 l bring the slotted cam 17 to a forward position, at which point the cam 17 will come to rest while the crank 15 continues its circular motion, the block 16 traveling around and in the slot 18 from top to bottornthereof, the cam 17 remaining absolutely stationary during the predetermined period, as clearly disclosed in the drawings. The saddle fork 24: of the cam 17 is brought into operative relationship with the pins 27 and 28 located in the cross head 20. The identical movements which bring the cam 17 into a forward position function to carry the cross head 20 with the revolving shaft 31 attached thereto forward also, the parts mentioned remaining stationary except for the revolving of shaft 31 during the desired period of time, after vwhich the blocky 16 makes a contact with the bottom of slot 19 and the cam 17 is then thrown back to its starting point, the shaft 31, therefore, functioning with an interrupted reciprocating motion, which constitutes a prime object of this invention.

In the operation of feeding suitable paper or other material to the machine and forming it into a desired tube, it is preferred that the paper 83 be delivered upon a table portion 84 of the machine suitably supported on brackets 85 attached to the main base portion 1 of the apparatus by means of machine screws 86 or otherwise. The paper 83, in ordinary practice, is delivered to the machine from a roll of paper 103 mounted on an iron shaft 104, which is Ynot a part of this invention, located in a convenient position to the tube forming'machine and functioning as a source of supply for the paper 83 which passes, in ordinary practice, from the roll 103 between adhesive rolls 105 and 106, positioned one above the other, the lower adhesive roll 106 being adapted to revolve in a receptacle 107 which contains an adhesive liquid. The paper 83 passing between the rolls 105 and 106 is properly spread with the adhesive.

The paper 83 is then delivered to the table 84C by means of a pair of rolls 87 and 88. The paper is ordinarily guided by hand and delivered between the rolls 87 and 88, which are mounted in Vbracket bearings 89 and 90 (see Figure 11), preferably connected in some proper manner to the table 84 of the machine. The lower roll 87 is preferred in this invention to be mounted in a fixed position in the bearings 89 and 90 while the upper roll 88 is mounted in adjustable sliding block members 91 (see Figure 28) which function to move in guide extensions 93 and 94, integrally a part of the bracket bearings 89 and 90.v The upper or free ends of the guide elements 93, 94, are heldin firm operative position by means of cap members 97 and 98 (see Figure l), through which suitable tension or set screws 99 extend for cooperation with compression springs 101, Awhich function to provide e. means whereby a. varying pressure may be exerted on the upper rolls f'or insuring. a proper degree of friction necessary forpulling the paper on to the table 84 of the machine. r1`his common form of tension device for paper feed rolls is used for adjusting the pressure of the upper roll 88 on the lower roll at each of the bearings 89 and 90. The upper and lower rolls 88 and 87 are mounted upon shafts or spindles 108 and 109. The lower shaft 109, kpassing through the roll 87, is adapted to have mounted thereon a spur gear 110, which is arranged to mesh with a similar gear 111, mounted upon shaft 108. The spindle 109 extends a suitable distance outwardly from' themachine inorder to accommodate a cable drum member 112, which functions to turnv freely on the shaft 109. The drum member 112 is vided with a cap member 115 suitably fas-V tened to the housing member 113 by means of machine screws 116 or otherwise. A series of dog members 117 are fastened tothe cable drum 112 in a suitable manner 'and function to engage theteeth of the ratchet 114, thereby providing an action in which, by rotating the drum 112 in one direction,

the lower roll 87 is made to revolve, thegear on the same shaft 110 imparting thesaine rotation to the upper roll, while a contrary movement will release the dogs 117 from the ratchet teeth 114, which will permit the drum 112 te rotate with a free actionk in the opposite direction. A cable or chain 118 passes around the drum 112' and connects with ak shackle member 119, pivotally attached to an adjustable sliding block element 120 by means of a pin 121. The sliding block 120 is adapted to mov-e in a fixed direction along a guiding portion 122 integrally a part of an arm member 123 having a longitudinal slot 124, in which is adapted to be slidably positioned a movable block 125 attached in a pivoted relationship tothe free endof a crank arm member126, which is properly mounted on a shaft k127, driven through suitable gearing 128 and 129, the gear 129 being mounted upon a shaft-130, which is.` in

` turn, rotated by meansfof a suitable sprocket wheel 131 mounted thereon and connecting, by meansy of a chain `drive 132 to a cooperating sprocket member 133 mounted upon a shaft 11. It is apparent that this arrange'- ment of elements provides 4a movement wherein the rotation ofthe crank 126 will cause the-arm member123 to swing back andYA forth with a rapid vmotion backward and a.

slower motion forward, ,at the same time tionin'g" to turn the rolls andthe sheet feeds' into the machine between the knife members 135 and136 and across the table. The sheet is then in position for cutting into the desired lengths and this is accomplished by means of a construction kwherein the knife member 135 is. adjustably bolted to the table portion84 alongan edge parallel with the rolls-87 and 88. Y'lhecooperating knife 136 is arranged to be supported by the standards 137 and 138'and in an upward and downward slidable relationship thereto, a movement whichis broughtfabout by means of 'a plate.n

member 139 slidably positioned in upwardly extending guide portions 140 and 141, which may be an integral part ofthe supporting brackets', or fastened to the standard elements 137 and`138, orotherwise, vthe knife 136 being'adjustably fastened. to the plate 139 in a proper manner, so that itsknife edge 142 will properly'cooperate with the knife edge 143 yof the member,135.The plate139 is held in slidableoperativepositionby means of' a plate 144, which extends between the guiding elements 137 and 138, and securely fastened thereto by mea-ns ,of screws 145 and'146 (see Figure 12) or otherwise. n The means for raising and lowering the plate `139, yto which the knife blade 136 is attached, vconsists primarily of a` pair of eccentricsv 147 and 148 mountedupon a shaft or spindle 149, which is rotatably supported in the standards 137 and'138.l Theplate 139 is preferably dctachably mounted! in the eccentrics 148 and 149, as'at 160, in sucha manner that the rotation of the eccentrics will function lto raise and lower the knife blade 136. The shaft149 isoperated from a` ota 1ly`connected,asat 156 to a crank member 157, which cooperates with another 'crank member 158, bothv of the cranks being mounted upon the same spindle Vor shaftv 159 in fixed relationship thereto. The spindle 159 is adapted to be supported in some suitable manner from the table ..84 by meansof a.` bracket 162 extending therefrom.V AV rocker arm member 163 is slidably connected at one` end to the crank 158 by means of a roller 164 which is adapted to beattached in some suitable manner to the free end of the crank 158 and adjusted to move within the slot 165 located in the rocker arm .163,- the other endV of the rocker arm 163 being supported in a freely moving manner upon the shaft 127.

vThe rocker arm 163 is provided, near its lower free end, with a roller element 166, which functions to extend inwardly and ride in the groove-167 of the cam 150, the shape of the groove 167 being such as to. impart upward and downward movement to the arm 163 when the shaft 151 is revolved, the up and down movement .being transmitted through the cranks 158, 157, crank link 154 and crank 153 to the shaft 149, and, in turn transmitted to the-knife 136, throughthe strapeccentric members 147 and 148 mounted upon the shaft 149. Any suitable means may be utilized for operatively connectingl the knife supporting plate 139 to the eccentrics 147 and 148. Y

As one modification of a means for accomplishing this purpose, suitable threaded lug extensions 168 and 169 are formed-on the stra-p portions 170 and 171 of the eccentrics, proper means'beingprovided along the upper edge of the plate '139 'for cooperating with the threaded lug portions in the yeccentric strap members, therebyy providing anv efficient means for imparting the desiredupand down movement to the knife blade 136. AIn this connection, attention is called to the fact that the groove 167 in the cam 150 is so form-ed that, directly following the up and down motion of the knife blade 136,'there is a distinct pause between the movements, thus permitting the removing Vof one sheet of paper out of the way and bringing another sheet across the table. The cam 150, being mounted upon the shaft 151, is driven by means of a sprocket wheel 172 keyed thereon and adapted to cooperate with a driving chain 173, which, in turn, meshes with the sprocket wheel 174 mounted on the shaft 11, which is drivenv in turn from the main shaft 2. Y v 1 The mechanism above described will function to feed the paper into the machine onto the `table 84 and cut the material intoproper size for kfurther operation. In order toY move the paper into cooperative relationship' `with the winding spindle 39, it is preferred, as one modification of this inventiomto pro-videa series of. slides 175, 176, and 177 suitably mounted in the Vtop 178 of the table 84 in such e a manner that the upper surfaces'of the slides will be flush with the tabletop. VThe* slides 175, 176, and 177 are operated preferably by shaft 180 is preferably providedwith a. XedV mutilated tooth beveled gear 184 and having attached thereto a stop plate185, the mutilated gear 184 being adapted-to mesh at a predetermined time with a pinion 186 and a cooperating plate 187 mounted upon a spindle or shaft 188, which is, in turn supported by suitable bracket or bearing portions 189. On the shaft or spindle 188 is adapted to be keyed a crank 190, to which ispivotally connected, as at 191, a connecting rod 192, which in turn connects in a pivoted manner, as by pivot 193 with an oscillating lever member 194, which is keyed to a shaft 195 suitably mounted in bracket or standard sections196 and 197 attached to a portion of the machine. A lever 198 is mounted in fixed relationship on the shaft 195 and is adapted to have pivotally connected to its free'end, as at 199 (see Figure 21), a link member 200, which is mounted at one end on a shaft 201. The shaft 201 is suitably mounted on bearings 202, 203 and 204, which are supported or attached in a proper manner to the slides 177,176 and 175. Itis apparent from this arrangement of members that the rotation ofthe crank 190 will function to rock the lever arm 194, thereby causing the slides 175,176 and 177 to move back and forth with an intermittent motion.

- Properly keyed-to the shaft 127 is a cam member 205, which functions to operate a lever 206 mounted upon a spindle 207, which is carried in bearing or bracket portions 208 and 209 fastened to aportion of the machine. A lever element 210 is mounted upon the spindle or shaft 207 and is of such a length thail functions to automatically raise and"lower the fingers 213 and 214 in such a manner as to permit the paper sheets to pass under the contact portions 217 and 218 and thento drop and hold the sheet in position after cutting and continuing the carrying forward movement of the slides 175,176, and 17 7 1n order to wipe the overlappingedges of the paper tube firmly together and as one.

ing with the cam 223, thereby providing af means for causing the wiping plate 219 to rise and fall at predetermined intervals, in order to wipe the overlapping edges of the paper firmly together before removing the tube from the winding spindle 39.

rllhe cam member 223 may be constructed of any suitable material and is adapted to be provided with openings 225 suitably spaced around the periphery and arranged in such a manner that a cooperating inem ber 226 may be adjustably attached to the main body portion 223 of the cam by means of machine bolts 227, thereby providing a cam device which may be adjusted for the proper operation of the wiping plate 219. In order to provide a proper tension to the wiping plate 219, a suitably formed spring element 228 is arranged to cooperate with the pivoted arm member 220 and the bracket portion 221.

It is preferred in this invention to provide means for cutting the tube into desired lengths before the article is withdrawn from the spindle, wherein the numeral 229 designates an adjustable sliding plate properly positioned upon an extension of the table member 84, as clearly disclosed in Figure 21 of the drawings. The adjustable plate 229 may be mace of any suitable material `such as cast iron, and is adaptedto be moved back and forth at pre-determined intervals by cam member 230 mounted in fixed relationship upon the shaft 151, and located `be neath the sliding plate 229. In order to operatively connect the cam 230 to the sliding member 229, ity is preferred in this invention to provide an opening 231 in the table portion 84 through which is adapted to extend a sliding block element 232 securely fastened to the plate member v229, the main portion of the sliding block 232 being adapted to ride in a specially formed groove 233 in the `cani member 230, in such a manner that when the shaft 151 revolves the plate 229 will move back and forthk a distance equal to the stroke of the sliding member in the groove.

Adjustably mounted upon the sliding plate member 229 is a guiding bracket 234, arranged to receive in slidable relationship thereto a series of dovetailed sliding blocks 235, adjustably arranged to carry a series of knife blades 236.

The guiding bracket esta provided with' openings 237 throughwhich suitable tension bolts 238 extend in such a manner that an advanced or retarded adjustment may be given tothe guiding plat-e 234 in relationship to the sliding plate 229. k'The sliding block members 235 are provided with lateral adjustment, each of the blocks being preferably made in two portions, the 'forward portion- 238rbeiiig dovetailed into'thc rear portion 235, and held in koperative relationship by means of a screw 239 capable of vertical adjustment to suitl requirements.

Each of the forward portions 238 of the.

siiding-block235 is formed having a groove 240 in which the knife blades 236 may be ade j ustably positioned.

The` sliding blockmeinbers 235 are adapted to be held in any desired lateral adjustment by means of a set screw 241. f

After Athe knife 136 has descended and cut the sheet into the desired size, the fingers 213 and 214 are descended and hold the severed sheet firmly againstthe slides 175, 176, and 177, the knife 136 having in the meantime returned to its normal position out of contact with the paper.- The slides then begin to move forward carrying the sheet of paper clearly designatedin kFigure 1by the numeral 244, the sheet stopping with the edge of the paper at a point j ust beyond the center of and beneath the winding spindle 39, which has meanwhile moved" forward simultaneously with the vforward movement of the` slides. AtA this instant thev wiping plate 219 rises lifting the edge of thepaper 244 and pressing it against the slotted portions 42 in the spindle 39, and cani member 245 mounted in fixed relationship on shaft 151 is adapted to actuate an'intake valve 246 through a series of levers 247and contact elements 248. l The intake valve 246 is opened connecting the valve with a vacuum tank which functions to produce a suction effect within the hollow portion 249 of the spindle 39, and functions to retain the paper firmly against the slotted portions 42 in the spindle.

Figure 32 clearly discloses the relationship within the valve'246` and .the spindle 39 Aat the time the spindle is in position for receivhaving received the sheet of paper, as K iso ing process has been completed, the guiding bracket 240 carrying the knives 236,V functions to come forward and cut the tube into desired lengths.

As the knives are Withdrawn the spindle `ceases to revolve and swings back, stripping the tubes therefrom in the act and a fresh sheet of paper is novv brought forward into position for another tube.

In operation this invention provides a paper tube forming machine in which the paper may be delivered by hand or other suitable means throughthe rolls and beneath the upraised'knife, power is then applied, the preliminary cutis made and the machine then functions completely once Without rolling the tube because there is nothing to roll.

Y Beginning at the point of the rolls the paper is delivered a full length sheet across the table beneath the proper members for carrying the sheet forward. At the desired position the sheet is cut off by the` action of theknife and the members for carrying the sheet forward come into operation, and thence advance the sheet to a position beneath the Winding spindle, Which meanwhile khas advanced to the required position; an additional member then comes into operation lifting the sheetk and pressing it firmly against the lateral slots in the Winding spindle, aided by vacuum means, after which the spindle begins to revolve and the tube is Wound.

A successive number of movements are pro- I vided at 'this point, not only to Wind the tube but topress the laps or convolutions of the tube firmly together. Simultaneously with the beginning of the Winding spindle revolutions, the members Which have carried the sheet forward, release themselves automatically and free the paper for the Winding operation. A

Following the Winding of the main tube, a series of mechanisms carrying anumber of cutting or trimming knives move to the desired position and sever the tube into sections of desired length. The cutting members then Withdraw automatically and the Winding spindle ceases to revolve, at thev same time starting abackWard movement which brings the tube sections against a nose block element thereby preventing their further movement and stripping them from the spindle. Y

It is understood that changes and alterations may be made in the above disclosure both in the specifications and drawings Within the scope of the appended claims Without in any manner affecting the merits of this invention.

' What I claim is:

1..In a paper tube forming machine, a reciprocating spindle mounted therein, means for revolving and stopping the rotation of the spindle at a predetermined period, means for yfeeding a sheet of paper intothe machine, means for cutting fthe'sheet of paper into the desired lengths, means for moving the sheet of paper, from the point of cut off to a desired position under the spindle, means for lifting and Winding the sheet of paper around the spindle, with its edges overlapping, means for wiping the overlapping edges lirmly together and means for cutting the tube into desired lengths and means for forcing the tube from the spindle on the retraction of said spindle.

2. In ak paper tube forming machine having a reciprocating Winding spindle, a crank member mounted upon a suitable driving shaft, a sliding block element attached to the free end of the crank, a cam member pivotally mounted at one end on a suitable portion of the machine, a slotted section in the cam for receiving the sliding blo-ck element, a saddle fork in the free end of the cam member, a cross head element for holding the Winding spindle in position, means on the cross head for cooperating with the saddle fork of the cam and bringing the free end of the. cam into a forward position, together with the cross head and revolving Windg spindle, the cam, cross head and spindle remaining stationary except for the revolving of the spindle during a period of time.

3. In a paper tube forming machine having'a reciprocating Winding. spindle, a mutilated gear and pinion for revolving and stopping the rotation of the spindle at a desired position, guide plates fastened to the mutilated gear and pinion in such a manner that they will function to remain yin contact during a partial rotation of the mutilated gear and automatically release themselves when the Vmutilated portion of the gear has yassed and again cooperates with the pinion,

thereby providing intermittent rotative mo- -tion to the Winding spindle.

In a paper tube forming machine having a reciprocating Winding spindle, means for delivering a sheet of paper to the machine for forming into a tube, means for moving the paper into cooperative relationship with the Winding spindle, means for giving intermittent motion to the movement of the paper, vacuum means for bringing the paper into firm Contact with the spindle, means for cutting the tube into desired lengths, and means for forcing the tube from the spindle on the retraction thereof.

In testimony whereof I aiiiX my signature.
